In netbios, there can only be one interface IP address for any netbios 
name.  Old MS problem, although I don't have any links.

I like to assign samba to only one of the interfaces and I assign the 
same interface to the DNS name.  Other interfaces get different DNS 
names.  This is useful in the kerberos world as well as paranoid ssh.

smb.conf
    interfaces = 192.168.3.x, 127.0.0.1

The 127.0.01 address doesn't register in wins or broadcasts and solves 
some broadcast issues, or at least it did a long time ago and I haven't 
experimented lately.
